Dinelli, Alberto. "Scalar active matter across scales". Electronic Thesis or Diss., Université Paris Cité, 2024. http://www.theses.fr/2024UNIP7003.
Texto completo da fonteActive matter encompasses out-of-equilibrium systems whose microscopic constituents exert non-conservative self-propulsion forces on their environment. The self-organization of active units into complex structures is observed at all scales in the living world, from bacterial ecosystems to flocks of birds. Furthermore, in recent years, physicists and chemists have been able to engineer synthetic particles capable of self-propulsion, such as self-phoretic Janus colloids or Quincke rollers, thus paving the way towards the realization of smart active materials. In this regard, understanding the link between the microscopic dynamics of active particles and their large-scale properties is a crucial problem for both biology and bio-inspired engineering. In this manuscript, we bridge this gap for a number of scalar active systems, i.e. active systems where the only large-scale hydrodynamic mode is the conserved density field. In particular, a large part of the manuscript is devoted to multi-component active systems---or active mixtures---whose study is relevant to achieve more realistic descriptions of biological communities: from animal ecosystems to bacterial colonies, polydispersity is ubiquitous in living systems. The manuscript is structured as follows. In Chapter 1 we provide a methodological review of coarse-graining techniques in scalar active systems. These methods are then applied in Chapter 2 to characterize the large-scale behaviors of non-interacting active particles with different tactic mechanisms. The second part of the thesis is devoted to collective behaviors in interacting scalar active systems. In Chapter 3 we study the impact of non-reciprocal motility regulation in binary mixtures of active particles, and show how the microscopic non-reciprocity affects the macroscopic organization of the system. Following this line, in Chapter 4 we consider a bacterial ecosystem where a large number of species coexist, revealing how weak, random motility regulation can be sufficient to promote the formation of distinct bacterial communities. To conclude, in Chapter 5 we shift from biological to synthetic active matter, studying a model for self-propelled Quincke rods. In particular, we show how these rods can undergo an arrested condensation transition, where the interplay between quorum-sensing and steric repulsion is crucial to stabilize the coexisting phases
Brahami, Yacine. "Mélange à scalaire actif dans les écoulements de jets turbulents". Thesis, Normandie, 2020. http://www.theses.fr/2020NORMR093.
Texto completo da fonteActive scalar mixing, which modifies the velocity field through variations of either density or viscosity, received much less attention than passive scalars. This thesis aims at unravelling some open questions pertaining to active scalar mixing. Whilst some results point to the facts that mixing occurs faster for i) light jets than for heavy jets, and ii) more viscous fluid released in a less viscous environment. This simple example reveals the necessity of a systematic study of the problem. We focus on two aspects of these very vast questions. I. Variable density round jet. We designed an experimental set-up, which allows measuring both velocity and scalar fields, using simultaneous Stereo Particle Image Velocimetry and Planar Laser Induced Fluorescence. The first question concerns mixing immediately after injection. Therefore, the very near field of the jet was particularly sought. One-point statistics were used to evaluate the large-scale effect of momentum and density variations on the initiation of turbulence. Also, two-point turbulent statistics for velocity and scalar have been appraised. Through this approach, the effects on transition were assessed through scales of turbulent motion. Mixing was also evaluated at the edge of the flow, in the vicinity of the Turbulent/Non-Turbulent Interface. We found additional specificity to variable density mixing, that is inaccessible by averaging on a cylindrical frame of reference. II. Temporally evolving turbulent jet flow with variable viscosity and mass diffusivity. The data consists in Direct Numerical Simulation performed in our group by Dr. M. Gauding. The purpose of these simulations is to study the kinetic energy and scalar dissipation rates in flows with variable momentum and mass diffusivities. We focused on conditional averaging in the vicinity of Turbulent/Non-Turbulent Interface. This data is confronted to one-and-two point transport equations for the momentum and scalar. It is shown that initial gradients of both viscosity and mass diffusivity have an intense and persistent impact on both kinetic energy and scalar dissipation rates, in the vicinity of the Turbulent/Non-Turbulent Interface, albeit a rapidly trend of the jet core towards self-preservation

Texto completo da fonteThe knowledge and the comprehension of the co-adsorption's phenomena present in many industrial processes, guided the realization of this memory. In a first part, and framework of NGV's topic with ANG technology, the importance of these phenomena of co-adsorption is highlighted. A series of 730 cycles of loading - unloading of a storage tank with NG was carried out. This one made it possible to quantify a total loss in the storage capacity of the tank of about 50 %. Moreover, by chromatographic analysis, the specific influence of each component of the GN was given. In a second part, a dynamic volumetry device, developed at the laboratory for the acquisition of co-adsorption isotherms of binary mixtures, was presented. From measurements carried out on a commercial activated carbon for the binary CH4 - CO2, this apparatus has been validated to 273 and 298 K, and for pressures going up to 1 MPa. The co-adsorption model IAST (Ideal Adsorbed Solution Theory), while using experimental isotherms of pure gases, was confronted with the results of the binary CH4 - CO2 : a lower deviation than 5 % was observed between computed values and experimental. The model MPD (Myers-Prausnitz-Dubinin), integrating the modeling of the isotherms of adsorption of pure gases according to the formalism of DA (Dubinin - Asthakov) in model IAST, was also tested and gives a good adequacy between computed values and experimental. This model MPD constitutes a particularly interesting and reliable working tool which could be easily integrated in simulation's models of industrial processes

Texto completo da fonteExperimental and theoretical studies have been carried out in order to obtain further knowledge and understanding of the corrosion behavior of silicon carbide under complex gas mixtures at very high temperatures. To that purpose, two original experimental methods based on Joule-heating have been designed for the in-situ following of SiC oxidation kinetics, and a model accounting for both heterogeneous kinetics and gas-phase transport phenomena has been developed thanks to a finite volume method. At high temperatures and low oxidant partial pressure, oxidation of SiC is « active » and associated with the formation of gaseous products and high degradation rates of the original materials, the reaction being rate-determined by species transport through a gaseous boundary layer. At low temperatures and high oxidant partial pressures, oxidation is « passive » and associated with the growth of a condensed oxide scale acting as a protecting diffusion barrier. An analytical study has been conducted in order to try and isolate the effects of the various physical and chemical phenomena involved during this passive oxidation, such as different growth mechanisms, volatilization or bubble formation, and quantify how temperature and gas composition influence them.An experimental study of the active/passive transition in the oxidation of SiC has been conducted under gas mixtures including one or two different oxidant species. Numerical simulation tools as well as new insights on oxidation mechanisms were used to analyze different predictive models of the active/passive transition and evaluate and understand the differences between these theoretical results and the ones obtained experimentally

Texto completo da fonteThe CASCADE company was founded to develop technology said to “light cascades”. These “light cascades” consist of incorporating an appropriate combination of optically active molecules (OAM) into host materials allowing wavelength-shifting effects to optimize the quality and quantity of direct and diffuse sunlight. When such OAM combination is introduced into greenhouse films, an increase of agronomic yields and early crop are observed. Such behavior is due to the fact that OAM allow to adapt the solar spectrum to the photosynthesis and the chlorophyll function of plants. Greenhouse films are based on polyethylene (PE) and/or poly(ethylene-co-vinyl acetate) (EVA) copolymers. When OAM are introduced within such host polymers, their optically efficiency is limited for long term industrial applications. Therefore, the thesis goal is to improve the OAM lightfastness into PE/EVA polymer matrix by different strategies: (i) the study of polymer matrix nature and topology influence, (ii) the optimization of current formulations by additives or compatibilizers adding and (iii) the OAM encapsulation into (un)-crosslinked PMMA particles
